更新時(shí)間：2023年09月25日 10:29:36 作者：笑的像個(gè)child
本文主要介紹了SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的實(shí)現(xiàn),其中也涉及到自定義的過濾器和處理器,具有一定的參考價(jià)值,感興趣的可以了解一下
前言
本項(xiàng)目主要是一個(gè)SpringSecurity+jwt+redis基于數(shù)據(jù)庫(kù)登錄認(rèn)證的Demo，其中也涉及到自定義的過濾器和處理器，希望能對(duì)大家有幫助，本文中所有代碼正常情況下可以直接復(fù)制使用。
一、前期準(zhǔn)備
1. 創(chuàng)建項(xiàng)目
勾選需要用到的框架
2. 引入相關(guān)依賴
提示：有三個(gè)依賴需要手動(dòng)添加，其余的在創(chuàng)建項(xiàng)目時(shí)就生成了

二、具體實(shí)現(xiàn)
1. 編寫配置文件
提示:修改數(shù)據(jù)庫(kù)的密碼，以及redis的端口號(hào)，我使用的7000，redis的默認(rèn)端口號(hào)為6379
server:
port: 8080
spring:
datasource:
url: jdbc:mysql://localhost:3306/javasec?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&rewriteBatchedStatements=true&allowPublicKeyRetrieval=true&allowMultiQueries=true
password: ****
username: root
driver-class-name: com.mysql.cj.jdbc.Driver
## redis配置
redis:
database: 0 # 數(shù)據(jù)庫(kù)索引 默認(rèn)為0
host: 127.0.0.1 # redis服務(wù)器地址
port: 7000 # 端口號(hào)
password: # 密碼（默認(rèn)為空）
timeout: 5000 # 連接超時(shí)時(shí)間（毫秒）
jedis:
pool: # 連接池配置
max-active: 8 # 連接池最大連接數(shù)（使用負(fù)值表示沒有限制）
max-wait: -1 # 連接池最大阻塞等待時(shí)間（使用負(fù)值表示沒有限制）
max-idle: 8 # 連接池中的最大空閑連接
min-idle: 0 # 連接池中的最小空閑連接

}3. 編寫dao層代碼以及mapper
UserDao中主要是通過username來查詢數(shù)據(jù)庫(kù)中是否存在這個(gè)用戶
RoleDao主要是用來查詢登錄用戶的角色列表（一個(gè)用戶可能有多個(gè)角色）
package com.javasec.dao;
import com.javasec.bean.User;
import org.apache.ibatis.annotations.Param;
/**
* @Author YZK
* @Date 2023/7/5
*/
public interface UserDao {
User loadUserByUsername(@Param("username") String username);
}package com.javasec.dao;
import com.javasec.bean.Role;
import org.apache.ibatis.annotations.Param;
import java.util.List;
/**
* @Author YZK
* @Date 2023/7/5
*/
public interface RoleDao {
List<Role> getUserRoleByUid(@Param("uid") String uid);
}<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<select id="getUserRoleByUid" resultMap="RoleMap">

where r.rid = ur.rid
and ur.uid = #{uid}
</select>
</mapper>4. 編寫springSecurity相關(guān)處理器
編寫UserServices
進(jìn)行身份驗(yàn)證之前，Spring Security會(huì)調(diào)用loadUserByUsername()方法來獲取用戶信息。該方法通常用于在數(shù)據(jù)庫(kù)中查詢用戶信息，然后將其封裝在UserDetails接口的實(shí)現(xiàn)類中，并返回給Spring Security。
package com.javasec.sec;
import com.javasec.bean.User;
import com.javasec.dao.RoleDao;
import com.javasec.dao.UserDao;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.Objects;
/**
* @Author YZK
* @Date 2023/7/5
*/
@Service
public class UserServices implements UserDetailsService {
@Resource
UserDao userDao;
@Resource
RoleDao roleDao;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userDao.loadUserByUsername(username);
if (Objects.isNull(user)) {
throw new UsernameNotFoundException("用戶不存在");
}
user.setRoles(roleDao.getUserRoleByUid(user.getUid()));
return user;
}
}登錄處理器
這個(gè)處理器中有兩個(gè)方法，onAuthenticationSuccess()方法主要用于登錄成功時(shí)為header設(shè)置token，并將整個(gè)已經(jīng)登錄的對(duì)象(authentication)存入到redis中，onAuthenticationFailure()方法主要用于登錄失敗時(shí)返回提示信息。

/**

*/
@Component
public class CustomAuthenticationHandler implements AuthenticationSuccessHandler, AuthenticationFailureHandler {
@Resource
RedisUtils redisUtils;
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
User user = (User) authentication.getPrincipal();
String jwt = JwtUtil.generateToken(user);
if (redisUtils.exists("login:" + user.getUid())) {
redisUtils.remove("login:" + user.getUid());
}
response.setCharacterEncoding("utf-8");
response.setContentType("text/html; charset=UTF-8");
redisUtils.set("login:" + user.getUid(), jwt);
response.setHeader("token", jwt);
response.getWriter().write(JSONObject.toJSONString(SystemResult.success("登錄成功")));
}
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
response.setCharacterEncoding("utf-8");
response.getWriter().write(JSONObject.toJSONString(SystemResult.fail(401, exception.getMessage())));
}
}Jwt過濾器
該過濾器可以攔截每一次請(qǐng)求，并驗(yàn)證header中是否存在token，驗(yàn)證成功則會(huì)通過UsernamePasswordAuthenticationToken傳給一個(gè)authentication provider驗(yàn)證成功則會(huì)返回一個(gè)帶有授權(quán)信息的身份驗(yàn)證對(duì)象。如果身份驗(yàn)證失敗，則應(yīng)返回一個(gè)未通過的身份驗(yàn)證對(duì)象。

}三、測(cè)試
1. 測(cè)試類
有兩個(gè)賬戶，一個(gè)是root,一個(gè)是user,密碼都是123456
先寫一個(gè)測(cè)試類，這個(gè)類中的接口需要有相關(guān)權(quán)限的用戶才能訪問
package com.javasec.controller;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @Author YZK
* @Date 2023/8/21
*/
@RestController
public class TestController {
//該接口需要admin權(quán)限才能訪問
@PreAuthorize("hasAuthority('admin')")
@GetMapping("/test1")
public String test() {
return "測(cè)試";
}
//該接口需要user權(quán)限才能訪問
@PreAuthorize("hasAuthority('user')")
@GetMapping("/test2")
public String demo() {
return "這是demo接口";
}
}2. 使用root賬戶登錄
訪問test1接口，沒有問題
訪問test2接口，被禁止，權(quán)限錯(cuò)誤的信息也可以自定義，本項(xiàng)目未自定義
3. 使用user賬戶登錄
同樣的登錄成功的信息
訪問test1接口，被禁止
訪問test2接口，訪問成功
redis中登錄成功存儲(chǔ)的jwt，有兩個(gè)賬號(hào)登錄，所以有兩條
總結(jié)
后端生成的jwt應(yīng)該存儲(chǔ)在redis中，每次處理請(qǐng)求時(shí)都應(yīng)檢驗(yàn)一次用戶的權(quán)限信息，以及jwt是否過期，在前后端分離的項(xiàng)目中，前端登錄后，后端生成的jwt會(huì)在請(qǐng)求頭中設(shè)置，然后前端拿到后，會(huì)存儲(chǔ)在localstorage中(只是舉例，想存哪兒隨意)，在前端發(fā)起請(qǐng)求時(shí)，也會(huì)攜帶著token到后端進(jìn)行檢驗(yàn)。
